NETWORK NODE, USER EQUIPMENT, METHODS THEREIN, COMPUTER PROGRAM PRODUCT, AND A COMPUTER STORAGE MEDIUM

摘要

Embodiments herein relate to a method in a network node (12,15) for managing transmit power of a user equipment (10) in a cellular network (1); wherein the network node (12,15) is comprised in the cellular network (1) and serves the user equipment (10). The network node (12,15) increases a power of a control channel of the user equipment (10). The network node (12,15) further limits a power increase of a data channel to a level by reducing a power of a serving grant of the user equipment (10) an amount, which amount corresponds to the increased power of the control channel. The network node (12,15) also reduces a reference value of the data channel for maintaining a transport block size of the data channel, which reference value determines mapping from the serving grant to the transport block size.
